Alright I searched all over and cannot find the answer. Here is my problem...Everything is fine while running on the primary injectors. I can even build up 3psi before the secondaries come on, but when the secondaries come on, under load, I lose power. It's like hitting a brick wall. I have everything grounded. My TPS is working fine. My SAFC has not changed settings. It will do this for a few days and then one day everything will be fine. Started doing this during a long drive. I was doing about 80mph when it happened for the first time, and now it is intermitting. Has anyone had this issue. The only thing I can think of that has changed is I did the transistor T801 fix about 2 weeks ago and this started happening last Sunday. Please let me know if anyone has had issues with the T801 fix. Oh by the way it is a S4 T2 Jspec no emissions SAFC

 

Anyone????
